Industrial Centrifugal Pump 1,200 L/min 78.4m — CA 50-250B
HIGH-EFFICIENCY COMPLETE SYSTEM: Pre-assembled EN 733 centrifugal pump set featuring a 18.5 kW motor that delivers water flow up to 1200 L/min with a pressure lift head reaching 78.4m.
MAXIMUM ENERGY SAVINGS WITH IE3 MOTOR: Driven by a premium IE3 efficiency-class electric motor (MOT160L frame) running at 400V, engineered to minimize electricity costs during continuous commercial and industrial operations.
TURNKEY BASEFRAME & COUPLING SET: Comes fully integrated on a rigid steel baseplate with flexible coupling and protective guard, ensuring zero shaft misalignment, low vibration, and extended bearing lifespan.
PRO-GRADE HEAVY-DUTY MATERIALS: Features a solid cast iron pump body, cast iron motor bracket, AISI 316 stainless steel pump shaft end, and customizable impeller options including cast iron, bronze, or stainless steel.
OPTIMIZED FOR BOOSTING: Handles clean, non-loaded liquids from -10°C to +90°C at operating pressures up to 10 bar, making it the ideal solution for boosting applications.
Product information
The Pentax CA50-250B+MOT160L is a complete, factory-assembled industrial horizontal centrifugal pump unit engineered in strict compliance with EN 733 European standards. Ideal for boosting applications, this turnkey pumping station delivers high hydraulic power and immediate operation readiness.
Powered by a premium IE3 high-efficiency 18.5 kW (25 HP) 2-pole electric motor (MOT160L frame), the CA50-250B hydraulic unit generates a flow rate up to 1200 L/min with a maximum head of 78.4 meters. The entire assembly is precision-mounted on a heavy-duty steel baseplate with a flexible drive coupling and coupling guard, reducing installation labor and preventing vibration.
Built to withstand heavy continuous duty, the pump incorporates a rugged cast iron pump body and motor bracket, a high-grade AISI 316 stainless steel shaft end, and a 20 mm ceramic-graphite-NBR mechanical seal. Supporting operating pressures up to 10 bar and fluid temperatures from -10°C to +90°C, the Pentax CA+MOTOR series offers customizable options including cast iron, bronze, or AISI 316 stainless steel impellers, counter-flange kits, and gland packing seals.
Impeller & Configuration Comparison:
-
Cast Iron Impeller (Standard): Reliable, cost-effective choice for clean water and daily pumping schedules.
-
Bronze Impeller (Optional): Prevents rust lock-up during long idle periods (essential for emergency fire-fighting) and offers superior resistance to sea water and cavitation.
-
Stainless Steel AISI 316 Impeller (Optional): Provides maximum resistance against aggressive chemicals, mild acids, and high temperatures.
-
Gland Packing (Optional): Traditional braided packing alternative to mechanical seals for environments with sand, sediment, or slurry.
Note: Fully assembled unit on baseplate with IE3 motor and coupling guard included.
